This application note describes a GC/MS method that resolves all EU and EPA PAHs, and known interferences, with the Select PAH column
The document addresses the difficulty in analyzing polycyclic aromatic hydrocarbons (PAHs) due to compounds with identical masses. It details a method that resolves all EU and EPA regulated PAHs, including difficult isomers like benzofluoranthene, using specific chromatographic conditions.
The note provides an optimized oven program for the Select PAH column (30 m x 0.25 mm) to achieve separation in a single run of approximately 45 minutes. It includes detailed tables listing the compounds, their molecular weights, CAS numbers, and retention times for both EU and EPA lists.
All EU and EPA PAHs are resolved in a single run with a runtime of 45 min.
